[An unusual form of silicosis caused by exposure to a priming putty (Asplit ET)].

A case report on a 59-year-old male patient is given who had been exposed for 30 years to silica flour when mixing the primer Asplit ET. To some extent the diagnostic findings were uncommon for silicosis and rather suggested the diagnosis of a usual interstitial pneumonitis. Only transbronchial lung biopsy and histologic examination inclusive energy-dispersing x-ray microanalysis was able to prove a complicated form of silicosis.
